SecureBlackbox includes internal non-documented functions to work with Base64 (Base64Encode, Base64Decode in SBUtils.pas). Unfortunately, there is no support for quoted-printable encoding (except that is available as a part of MIMEBlackbox) available.

I'm note sure it is a qotedprintable encoding. I'm joining the file + sig file to this message.
Windows can open this .p7s file, could you said me if i can used a component of eldos to read this type of signature ?
